Ambry Genetics

Dec 27, 2023

The c.754C>A (p.L252M) alteration is located in exon 6 (coding exon 5) of the WDR93 gene. This alteration results from a C to A substitution at nucleotide position 754, causing the leucine (L) at amino acid position 252 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
